Everyone; this whole thing is still going on, it's not really that hard to make a booth. Make one if you have any sort of project you would like to show off, at this point I'd almost
be inclined to suggest arcade games to fill up the empty spots, or really anything that is going to fill them up. Not to mention the actual building for blockoworlds must be finished.
Munk; there really shouldn't have been a due-date for booth sign-ups, a week prior to opening day is plenty of time for someone who is committed and able, to set up their booth.
